Over a thousand private jets have landed at the Swiss mountain ski resort of Davos, where the planet’s elected presidents and unelected financial rulers have gathered for the World Economic Forum. There, they discuss the fate of the world.

Among those attending are billionaire investors and CEOs of global companies—which is one of the reasons why Donald Trump, the first US president to attend the gathering in 20 years, also made the trip.

Beneath the glitz, the gathering features star-studded panels on how businesses and governments can solve the world’s problems. This year’s program calls for new efforts toward “developing a shared narrative to improve the state of the world.”

To those gathered this coming week in Davos, here’s another idea: Come home. And bring your wealth with you.

At a time when the eight billionaires hold as much wealth as the bottom half of the world—and when three US billionaires have as much wealth as the bottom 50% of US households combined—it’s time for drastic action.
